In this light, RT chiral spin textures, consisting of a large range of topological spin textures with fixed handedness (Section2c-e), have gained traction for practical device implementation due to their energy-efficient SOT-driven dynamics. [1]}, [2]}, [3]}, [4]} These textures have been stabilised in various HM/FM and HM/FM/oxide multilayers including the pinning-free Pt/CoB/Ir, Ir/CoB/Pt and Pt/CoB/MgO amorphous material platforms.[5]} Here, we reported that PMA can be enhanced through controlled intermixing within the metallic Pt/CoB/Ir and Ir/CoB/Pt stacks, and thermal annealing across the three amorphous stacks. This provides a means of K\(_\mathrm {eff}\)  tuning for a range of chiral spintronics-based technological applications.
